SEED-PLANTER.

SPECIFICATION forming part of Letters Patent No. 295,297, dated March 18, 1884.

Application filed November 24, 1883. (No model.)

To aZZ whom it may concern:

Be it known that l, Assam; SMITH, of Ghatham, in the county of Kent, Province of Ontario and Dominion of Canada, have invented a new and useful Improvement in Seed-Planters, of which the following is a full, clear, and exact description.

Reference is to be had to the accompanying drawings, forming a part of this specification, in which similar letters of reference indicate corresponding parts in all the figures.

Figure 1 is a rear elevation of a seed-planter to which. my improvement has been applied, parts being omitted. Fig. 2 is a plan view of the seed-dropping slide and a part of a camwheel. Fig. 3 is a sectional rear elevation of my improvement, showing a part of the drive-wheel and a part of the seed-dropping slide. Fig. i is a side elevation of the flanged wheel that carries the cam-wheel. Fig. 5 is a side elevation of the cam-wheel. Fig. 6 is an edge view of a part of the same. Fig. 7 is a side elevation of the wheel-holding springs. Fig. 8 isa side elevation of a modified form of cam-wheel. Fig. 9 is an edge view of a part of the same.

The object of this invention is to promote accuracy in the operation of seed-planters, and also to facilitate the adjustment of the seeddropping mechanism.

The invention consists in the construction and arrangement of parts, as will be hereinafter described and claimed. I

The cam wheel is seated upon a flanged wheel attached to the drive-wheel, where it is held in place by springs engaging with ratchet-teeth in the inner edge of the said wheel, and attached to a band placed upon the drivewheel hub, so that the seed-dropping slide will he operated with certainty, and the cam-wheel can be readily adjusted, as will be hereinafter fully described.

A represents the wheels; B, the axle; O, the seed-boxes; D, the seed-coiulucting spouts; E, the seat-standard, and F the seatof an ordinary seed-planter.

G- is the seed-dropping slide, which passes through the lower parts of the seed-boxes O, and has apertures H formed in it to receive seed from the seed-boxes C and drop it into the spouts D.

' To the spokes of one of the wheels A is secured, by hook-bolts I, or other suitable means, an annular wheel, J, having a flange, K, around its outer edge, to form a seat for the annular wheel L, which has serrated cams M formed upon its side to operate the seeddropping slide G to drop the seed.

Upon the side of the annular wheel L, between the cams M, are formed lower cams, N, to jar. the seed-dropping slide G when its apertures H are in position to receive seed, and thus cause the seed to enter the said apertures.

Upon the inner edge of the annular cam wheel L are formed ratchet-teeth O, with which engage the outer ends of three (more or less) springs, P, the inner ends of which are attached to a band, O placed upon the hub of the drive-wheel A. The springs P hold the cam-wheel L to its place upon the flanged wheel J, prevent it from sliding upon the said wheel, and allow the said caniwheel to be readily adjusted to cause the seed dropping mechanism to drop the seed in line with the cross-rows of the hills previously the frame of the planter, and pressing against a pin, U, or other rest, attached to the said slide G.

Having thus described my invention, I claim as new and desire to secure by Letters Patcut- 1. In a seed-planter, the combination, with the drive-wheel A and the spring-held seed dropping slide G, of the flanged wheel J the cam-wheel L, having interior ratcl1ct-teeth, O, and the springs and band 1? Q, whereby the said seed-dropping slide will be operated with per-slide, and cams N between said cams M, certainty, and the cam-wheel can be readily for jarring the dropper-slide, substantially as adjusted, as set forth. set forth.
